NSX-T Logical Routing

This book is a one-stop guide for IT professionals with a background in traditional and software-defined networks looking to expand or hone their skill set and has been developed through a combination of extensive research and testing in both development and production environments. It provides reliable information on a fundamental component of NSX-T, logical routing.

A comprehensive understanding of this capability will help IT professionals with design, implementation, troubleshooting, and enhancements.

The book starts with an introduction to the foundational components of the NSX-T platform and how NSX-T fits into the software-defined data center. The focus then moves to tunnel endpoints, which is a critical aspect of the NSX-T platform, and the differences between overlays and underlays are explained. Once the basics are covered, it provides a detailed description of how NSX-T components communicate.

Next, the book introduces logical routing and its components and provides a better understanding of how these components function with one another. Several packet walks are illustrated to explain NSX-T logical routing behavior in different scenarios. After mastering logical routing, it explains how NSX-T ensures data plane availability, which is explored at various layers of NSX-T.

Finally, the book explores the concepts and intricacies of routing into and out of the NSX-T environment. It deep dives into utilizing the Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Static Routing.
